400X Hydraulic Automatic Control Valve Type Pressure Reducing

400X flow control valve is a valve that uses path pilot mode to control flow. It is suitable for devices that need to control flow and pressure in water distribution pipes. It maintains a predetermined fixed flow rate, limits excessive flow to a predetermined value, and maintains an appropriate upstream high pressure. Even if the pressure upstream of the main valve changes, it will not affect the main valve. downstream flow. This closure is a change from conventional throttle valves using orifice plates or purely mechanical ones to reduce energy flow losses during the throttling process. In case of emergency, the 400X flow control valve can completely prevent flow and loss in advance. The control is identical, completely reliable, debugging is necessary and the service life is long. It is widely used in industrial water supply and high-rise building direct water supply systems from water pumps.

Automatic hydraulic control valve Working principle:

​ 400X Flow Control Valve When the valve supplies water from the inlet, the water flows through the needle valve into the main valve control chamber, and bypasses the main valve control chamber through the pilot valve and ball valve to reach the outlet. At this time, the main valve is in a fully open or floating state. The flow regulating valve above the regulating valve can set a certain opening of the valve. By adjusting the needle valve opening and the pilot valve spring pressure, the main valve opening can be maintained at the set opening, and the pilot valve will automatically adjust when the pressure changes to keep the flow rate unchanged.

Adjustable water flow regulator valve Features:

1. Easy maintenance, debugging and inspection, reliable sealing and long service life.

2. The valve body adopts a full-channel streamlined DC design, with small liquid resistance and large flow rate.

3. Using hydraulic self-control, no other devices and energy are needed to ensure necessary and stable flow control.
